INSULA'IOR.

Specification of Letters Patent.

Patented Aug. 1'7, 1915.

Application filed October as, 1914. Serial No. 869,045.

To all wit-0121, it may concern:

Be it known that we, ZEN W. NEELY and GEORGE A. LEWIS, citizens of theUnited States, residing at Rayland, in the county of Jefferson and Stateof Ohio, have invented a new and useful Insulator; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will'enable others skilled in the art to which itappertains to make and use the'same.

This invention relates to an improved insulator for the connection oftelegraph and telephone wires.

As an object of the invention it is the aim to provide an insulatorcomprising two members constructed of glass or other similar materialand having threaded connections, one of said members being provided withtwo different series of concentric grooves, one series being deeper thanthe other, each series having different lateral outlet grooves, so thatdiifer'ent series of wires running in different directions may beconnected to the insulator. The other member is provided with a seriesof annular ribs or tongues to engage-in the innermost grooves of thefirst member, thereby holding the wires in the grooves insuch a manneras to prevent short circuit by the wires contacting, where one set ofwires leave the insulator.

In practical fields the details of construction may necessitatealterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings :-Figure l is a view in section of the improvedinsulator. Fig. 2 is a view of the two parts or members of the insulatorseparated, showing their adjacent faces facing each other, therebydisclosing the two sets or series of grooves in one of the members. Fig.3 is a plan view of the base member, showing the two sets of grooves,showing the wires leaving in different directions.

Referring to the drawings, 1 designates the base member of the insulatorhaving a threaded bore 2 to engage a screw 8 of the cross bar of atelegraph pole. The base member 1 has a screw threaded stud 4 to engagethe threaded bore 5 of the other member 6 of the insulator. The face 7of the base member 1 is provided with two series of grooves 8 and 9, theseries of grooves 9 being deeper than the grooves 8, and are designed toreceive the ribs 10 of the member 6, so as to hold. the wires 11 in saidgrooves, in order to prevent said wires from contacting with the otherwires in the grooves 8, which would cause short circuiting. The grooves9 are provided with outlet grooves 12, which extend in differentdirections than the outlet grooves 13 of the grooves 8. By this methodtwo sets of telephone or telegraph wires may be connected to theinsulator in such a manner as to extend in different directions. Themember 6 is provided with lateral lugs 14 so as to enter the lateralgrooves of the annular grooves a so as to insure the wires againstcontacting.

The invention having been set forth, what is claimed as new and usefulis 1. An insulator for electric wires comprising two members, a basemember and a head member having threaded connections,

one of said members having two sets of annular grooves, each havinglateral outlet grooves for the reception of wires, the head memberhaving means to hold the wires in one set of said grooves.

2.. An insulator for electric wires comprising two members, a basemember and a head member. the adjacent faces of which have threadedconnections, the adjacent face of one member having two sets of groovesone deeper than the other, and each set of grooves having lateral outletgrooves, said grooves acting to receive wires, the adjacent face of theother member having a set of annular ribs or tongues and provided withlugs or tongues to engage the deeper grooves and their outlet grooves ofthe adjacent face of the other member.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
